LP87702-Q1: Alternative replacement LP87702DRHBRQ1

Part Number: LP87702-Q1
Other Parts Discussed in Thread: TPS65653-Q1

Hi There,

Our product is using LP87702DRHBRQ1 in our design. Unfortunately, this power chip is out of stock for quite a long time. And lead time are extremely long. So here I am asking for help: any alternative chips could replace it? Both automotive grade parts and industry grade parts are good to me. And I only use the buck voltage (3.3->1.8, 3.3->1.24).

Thanks and Best Regards

Hi Dong,

Are only the two bucks whereas boost is not required? What are the load current requirements for the rails? Do you need I2C?

Best regards,

Thanks Samuli. 1.8V rail is 850mA. 1.24V rail is 2A. I2C is not necessary.

Best Regards

Hi Dong,

TPS65653-Q1 is in stock and could be a replacement but the output voltages are not an exact match. TPS65653-Q1 has two 3A bucks and they can be configured via I2C. Would this part work for you?

Best regards,
